Package

Abstract

A package formed from a cardboard blank having crease lines and wall panels, bottom flaps forming a bottom of the package and top flaps, namely short-side flaps and long-side flaps, folded and heat sealed together to form the top of the package. One of the long-side flaps has at its free end a seal tab, which is provided with a heat seal adhesive and is sealed against the opposite long-side flap. The seal tab has a smaller length than the width of the package for enabling it to be brought down into the top of the package for re-closing thereof.

Description

TECHNICAL FIELD[0001]The present invention relates to a package, which is made of a cardboard blank with crease lines and has wall panels, bottom flaps forming a bottom of the package, and top flaps, namely two long-side flaps extending unbroken over the width of the package and two short-side flaps, said top flaps being folded and heat sealed together to form a top of the package, which may be of the gable top type or the parallelepipedical type.BACKGROUND OF THE INVENTION[0002]Dry foodstuffs, like cereals, meal, and gruel, are most often packed in cardboard boxes or packages of the gable top type or the parallelepipedical type. For different reasons, it is customary to make the cardboard of waste fibres and to pack the foodstuff in an inner bag of for example plastic, which preserves the foodstuff in a good condition, until the bag is opened, and prevents the foodstuff from getting in contact with the waste fibre cardboard.[0003]Coated cardboard materials of virgin fibres are now ...
